Unity3D中的JSON.Net中的MissingMethodException webplayer

Question

我在Unity3D上使用JSON.Net 5.0r6序列化對象，dotnet 2版本。我可以在編輯器構建中的Webplayer模式下正常運行，但是當我部署到Webplayer時。我收到一個丟失的例外。我可以得到相同的代碼在Android上運行良好（沒有剝離），所以它不是代碼端。

MissingMethodException: Method not found: 'System.Collections.ObjectModel.KeyedCollection<System.String,Newtonsoft.Json.Serialization.JsonProperty>..ctor'.

Answer 1

發現了另一個類似的問題，似乎是Unity3D screwup再次

Answer 2

不幸的是，在JSON.Net實現與使用KeyedCollection（最初在mscorlib程序）中的問題。

對我來說，解決辦法是更換LitJson.dll

只有兩個方法整個實現，實際上我從JSON.Net用的都是

//JSON.Net 
    JsonConvert.DeserializeObject<YourClass>(jsonSring); 
    JsonConvert.SerializeObject(yourObject); 

，你可以很容易地

改變他們

//LitJson 
    JsonMapper.ToObject<YourClass>(jsonSring); 
    JsonMapper.ToJson(yourObject);
